Kennametal 1113573 Grooving Insert NG2062 K68 Carbide

Product Description

The KENNAMETAL 1113573 is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and similar machine tools. Manufactured in the NG style as part of the Top Notch series, this insert features a 1.58 mm cutting width and a maximum depth of cut of 2.79 mm. The K68 grade is an uncoated, bright-finish carbide formulated for applications where a hard, wear-resistant edge is required. With a neutral rake geometry and a 55-degree included angle, it is suited for consistent, controlled material removal in grooving and parting applications. This insert is installed and applied by machinists and toolroom technicians working in precision machining environments.

This insert is intended for left-hand grooving operations on lathes equipped with compatible Top Notch series toolholders. It is well suited for grooving external diameters in production and job-shop environments where metric tooling is specified. The NG2062 insert size and K68 carbide grade make it appropriate for machining non-ferrous materials and cast irons, where an uncoated carbide edge performs reliably. The corner radius of 0.19 mm provides a modest edge break without introducing a full-radius profile, making it suitable for applications requiring defined groove walls.

Key Features

• Solid carbide K68 grade, uncoated bright finish for consistent edge integrity
• 1.58 mm cutting width for narrow, precise groove profiles
• Maximum depth of cut of 2.79 mm, within the 2.00 to 3.00 mm depth-of-cut range
• Left-hand orientation for compatible Top Notch series toolholder setups
• Neutral rake geometry with a 55-degree included angle for controlled chip formation
• Corner radius of 0.19 mm for defined groove wall geometry without full-radius profile

Compatibility

Designed for use with Top Notch series toolholders that accept the NG2062 insert size in a left-hand configuration. Confirm toolholder seat style and clamp type before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder seat for debris or wear before seating the new insert. Do not use damaged or chipped inserts, as this can affect dimensional accuracy and workpiece finish.
